The four scientists were recognised for important contributions to statistical mechanics and for using it to investigate complex systems, with applications in areas such as biological systems, financial markets and artificial intelligence.
Deepak Dhar – Why is he important?
Prof. Deepak Dhar is an Indian theoretical physicist known for his contributions to statistical physics and stochastic processes.
His work has been particularly influential in understanding complex systems and self-organised criticality.
One of his best-known contributions is the Abelian sandpile model, which provides a mathematical framework for studying how interactions among many components can produce large-scale and seemingly unpredictable events.
